This object is accomplished by means ot' a breeclrcap consisting', substantially, of a metal cap, iu the bottom ot' which a hole is made a little larger than the bore ot the gun, and through which the cartridge and shot are introduced into the gun. This cap is shown by A, and the hole in its Vbottom by B. of this cap a screw-thread is cut to screw into a like thread cut on the breech in the manner shown by 11`ig. 2. The breech ot' the gun is thus embraced by a metal cap having a hole iu its center, through which the charge is in'- troduced into the gun. Now, to close the bore ofthe breech, l tit a breech-plug. c, iu the bottom ot' the cap aud secure it there by means ot' an arm, D, bolted to the cap, the plug swinging by the arm about the bolt as a pivot, so that the plug turns with the cap and travels laterally to and fro with it. Thus, when the plug is in the position shown by the drawings, it covers thc hole iu the bottom ol' the cap and closes tbc breech ot' the gun; but when the cap is screwed back the brecchplug l'ollows it und drops' down iuto the side ot' the cup, as shown in dotted lines, there being a recess, l), cut in the side of the cap to receive the breech-plug,

which, though it is pivoted by the arm l) to' the bottom ot' the cap, is, nevertheless, l'ree to t'all into the recess clear ot' the bore ot' the gnu and the hole in the .bottom ot the cap', and the position ot' the arm that secures the breech-plug' in the bottom ol' the cap, with ret'- eretico to the lateral motion of the cap on the breech of the gun, is such that iu screwing the cap forward the breech-plug automatically takes its scat into the bore ot` the gun. To draw the plug back out ot its seat in the breech ot` the gun there is a flange or collar, r, made around its rear cul where itjoins against. the bottom ot' the cap aud upon one side ot' [lange opposite the arm ot' the plug, and against the bottom ot' the cap a cleat,`.r, is litted, by which the plug is dravfu back and securely held against the bottom ot' the cap. .This cleat is to be snugly titted upon thecollarot' thel plug, so that the i'rictiou ot` the cleat upon the collar will arrest or break the t'all ot` the plug into the recess ol' the cap. The cleat must, ofcourse, be made and set upon a circle ol' which the diameter ot the plugaud the length ot the arm is the radius, the cleat thus making, also, a guide and groeve to govern and soften the fall ofthe plug. By these means the breech-plug can be remove d from its seat, the gun loaded, and the breech-plug replaced without. taking the breech-ca ott' the gun.

The object. ot' the second. ot' my said improvements is to give greater strength und durability to the supplemeutal-charge chambers and at the same time facilitate the coustruction o' the gnu. This object is accomplished by making the supplementalcharge.

lu the iuside'of'the tiangeY bored; whereas, when these chambersrareVVV .Y

made Yiu-the metal ofthe gun, they rapidlyr deteriorate, and the boring and fitting of them is a work ot' great difficulty. l

The object ot' my third'improvement is to provide a better means ot` loading the supple ymeuml-charge chambers. To accomplish this object I make the priming-hole as large as possible, having d ue. regard to the strength ofthe gun, and fit it with a primingplug ofthe coustruction substantially illustrated by Figs. 6 and 7 ot' the drawings. This priming-plug is made ot' bronze meta-l and coussts,iirst, ot'a tubular sermv-plug or bushing, ("r, vthat screws.l

solid in sockets ol corresponding shapefcut in the top olf the gun over each supplemental chamber. ln this tubular screw-plug is ttted a tubular key, Il. rthis key accurately tits the plug tr, in which it is held by means ot' shoulders a u, made ou opposite sides ott it and arranged to lock under shoulders b b, ot' correspending shape, made ou the inside of the tu bular plug or bushing (l, as shown by-Figs. G

and 7. The shoulders ot' the key H enter the tubular plug if through grooves ot' corresponding shape, cut into its upper end, and then by turning the key its shoulders lock under the shoulders ofthe screwplug, as above described, and the two shoulders, by heilig made slightly wedge-shape, draw thekey down tight into its seat. In the tubular key H there is accurately tit-ted a solid plug, I, ou the upper part ot' which a screw-thread is cut that matches a similar thread eut in the key. ly this means the plug l' can be screwed to and fro in the key. Now, the lower end ot' the plug I accurat'ely lits the lower end otthe priming-hole, and should be madesmooth and protected from bruises when the plugis removed from the gun. 1t is t'or thel purpose ot' prtytecting the nicely litted end ot' the central plug, l, that it is placed inside ot the tubular key, ot' which it is really a part., back into which it cau be screwed, and by which itis thus protected, as in a sheath, when removed from the gun. To charge the IIO supplemental chambers, therefore, the plug I mustbe screwed back into its key, which must be unlocked and removed, the plug I comingout with the key, thus opening the `priminghole to the chamber. The top of'thc plug'or bushing (l is covered with a t'ap,' fc,`litted closely aroumlthe top ol' the key, which must be made square, to receive a wrenelrby which it is to be locked and unlocked; and the same is truc ot' the top ot' thc central plug, I, which must alse be titted with a crank or wrench byl which it is to be operated. The bearing ot' the lar screw-bn'bing" fitted with :L tubular key I charge chamber made wholly, of steel o rvwith containing` and shieldingor protecting' a, solid :in entire steel lining, the two being united t0 central screw-pin, substantially as described. forni :L continuons facing' 0f steel.
